摘要
采用基于非期望产出的超效率SBM模型,测度2005-2017年长江经济带沿线11省份绿色经济效率,考察其时空格局的演变特征,采用空间杜宾模型实证分析其影响因素。研究结果显示:长江经济带绿色经济效率呈先升后降趋势,省际差异呈先缩小后扩大趋势;长江经济带绿色经济效率具有显著的空间自相关性,相邻省份的经济发展水平、对外开放度、环境污染治理对周边省份绿色经济效率具有正向促进作用,第二产业占比具有负向抑制作用。进一步提升长江经济带绿色经济效率,必须推动产业结构优化升级,提升对外开放质量,加大环境污染防治力度。
Using the super-efficiency SBM model based on unexpected output,this paper measures the green economic efficiency in eleven provinces along the Yangtze River Economic Belt from 2005 to 2017,followed by an investigation of the evolution law of their spatial and temporal patterns,as well as an empirical analysis of the influencing factors by using the spatial Durbin model.The results show that the green economic efficiency in the Yangtze River Economic Belt exhibits a pattern of first rise and then fall,while the regional differences feature a spatial evolution of first narrowing and then expanding.A significant spatial autocorrelation of the said efficiency can be seen in the fact that adjacent provinces all exert positive effects on the green economic efficiency in the neighboring areas with their level of economic development,openness and environmental pollution control,while negative effects are observed with their proportion of secondary industries.To further enhance the efficiency of green economy in the Yangtze River Economic Belt,it is,the paper indicates,highly necessary to promote the optimization and upgrading of the local industrial structure,improve the quality of opening drive and strengthen the prevention and control of environmental pollution.
